Firefox, simple and easy to use. Not to mention that I can go to all kinds of shady sites looking for cracks and such, never get viruses. But the first time I go there in IE I get swamped by tons of stuff. Safari? I used it when I had an iMac G5, but I don't use it much on my PC. I may have used Safari when I went to PC, but it was still when certain sites had small issues with Safari, like certain decals and such not lining up. Stuck on Firefox, especially after 3.0, still have the download certificate PDF ^_^
